Semi E132.1

SEMI E132.1 defines the SOAP web-service binding for equipment-client authentication and authorization — the actual WSDL-defined login/credential-exchange operations, SOAP header structure for carrying a session token, and fault-response schema for a rejected or expired credential — rather than the general "clients must be authenticated and authorized" requirement E132 establishes. E132 says equipment must verify client identity and enforce a permission level before acting on a command; E132.1 is the transport-binding companion that fixes precisely how that identity gets exchanged and carried on the SOAP-based web-services infrastructure the EDA/Interface A family (E125.1, E134, E164, and the rest) already runs on, the same relationship E125.1 has to E125 — now applied to the authentication layer instead of equipment self-description.

SEMI E132 says: verify identity, enforce a permission level
A requirement, not a defined credential-exchange mechanism
SEMI E132.1 — SOAP binding for equipment-client authenticationFixes the WSDL login operations and SOAP header token structure
Defined WSDL operations for credential exchange and login
Same web-service call signature across every compliant tool
Fixed SOAP header for session tokens, fault schema for rejections
No vendor-specific interpretation of how auth failures are reported
Host's SOAP-based EDA client authenticates the same way everywhere
Works alongside existing SOAP-based E125.1/E134/E164 integrations

The reason E132 needed its own transport-binding standard is the same gap every EDA/Interface A specialization closes the same way: a requirement to authenticate and authorize clients in prose still leaves the actual login call, token format, and failure-reporting schema open to each equipment vendor's own implementation, so two E132-compliant tools could demand login in incompatible ways the host's SOAP client would have to special-case. E132.1 removes that gap by binding the authentication exchange to the same SOAP/WSDL pattern the rest of the Interface A family already uses, so a host's existing SOAP-based EDA infrastructure can add standardized login and session-token handling as one more defined call rather than a per-vendor credential negotiation.

The Actual SOAP Envelope E132.1 Fixes "must authenticate" still needs a defined call to exchange credentials Request — Login operation <soap:Envelope> <soap:Header> credentials <soap:Body> LoginRequest(user, cred) fixed WSDL operation Equipment validates against E132's model Response — session token <soap:Envelope> SessionToken + permission tier Fault schema used on reject / expired credential Two E132-compliant tools could still demand login differently E132.1 fixes this exact envelope shape — header, body operation, token field, and fault schema — identically for every vendor

E132.1 completes equipment-client authentication the same way every ".1" protocol binding completes its base standard: E132 defines that identity must be verified and permissions enforced, and E132.1 is the fixed SOAP/WSDL mechanism that makes the actual login exchange and session-token handling identical across equipment vendors, so a host's EDA client never has to special-case authentication by brand to connect securely.
